To all whom it may Concern;

Be it known that IfI-IueoPnTnasnn, a chemical engineerpand a subjeet ofthe German Emperor, and a r'esidentof 1-8LKaiser- Alle, in the cityjofWilinersdorf, near Berlin,

Kingdom of Prussia, and German Empire,

have invented a certainnew and user'nlFillmg Material forReaction-,Cl1ambers,' of

which the following is a specification.

This invention has for its ob'ect to provide a packii'ig orfillingmaterial for reaction chambers, absorption chambers, gas puriliers andthe like, constructed and adapted to be arranged in such manner thatgases and liquids maybe brought into intimate contact eaclrwiththe'other, so that eachwill permeate and be. caused totreact perfectlyupon the other, i I

'The invention is intffnded to secure the highest degree of efficiencyin theabsorption of vapors or gases by liquids, to cause the removal ofsolid impurities from gases or va-v pors, and to avoid the tionsby ilucdust andt 10 like. The packing material, forming the sub'ect of thisinvention, is composed ofperfor ted plates arranged in pairs at anangle, oroppositely inclined with relation to each other, the plates ofeach pair, being either separable or permanently connected to eachother, and presenting a roof shaped structure, the top or meeting edgesof theplates forming a substantiall y horizontalridge.

The oppositely-inclined plates are rovided with horizontal perforations,and tieir end faces are preferably so arranged as to permit the platesto stand inclined against the horizontal, and to be supported againsteach other. The plates of each pair may eitherbe detachable fromeachothor or they may. be made in one piece, so as to constitute anintegral roof-shaped structur Alarge number of such hppositely-inclirangedlsideb sir e 11 nectedfifdes: gated. structure made n pairs'ofplates; lThe tegrally com right angles to said rig Lion is ietw firangement of perfo tio' tions ,erinit the liquid o go, though myinven:

v -ip,s,l down u-pon tic outer sides; to flowthi ough u'pon liquid fromone surface to the other.

and at the-same time the gases are free to flow u on both surfaces. Theinclination of the p ates compels the ascending gases to im-- pingeagainst the inner sides of the plates and to flow through theperforations and along the outer sides, thereby becoming intimatelymixed with the liquid, which in its turn, rebounds from the outerinclined surfaces of the plates, and thereby becomes sprayed into atoms.An intimate reaction and mixture of said spray with the jets of gasesemanating repeatedly su )divide and reunite the differ-' ent particlesof the gases and liquid. The ascendim gases are reflected by the opositely-indlined surfaces of the adjacent pfittes to a large extent,and rebound from one surface against the op osite surface, so that theare compelled to flow several times throug the same space and to passthrough the holes in the plates during the whirling motion imparted tothem. By this means an intimate contact of the reagents is produced, anda large area of acting surface is provided. Any flue dust carried alongwiththe gases is either reflected on the inclined surfaces or-iscompelled to slide down the inclines, so that deposits of flue dustwhich might interfere with the operation of the chambers filled withsaid There is therefore no liability of any injurious reduction ofdraft.

The airs of plates may be arranged at an. desirer distance from eachother, so that 1t is possible to change the distance between the airs inseveral parts of the reaction chamier, without any liability of theupper rows dropping or breaking down, even when arrangm the said bodiesat a considerable distance from each other. 'In case some liquid shouldcollect at the lower edges of the dates, the then descending jet ofliquid will be reflected, ,and converted into a spray by the plates justbelow. In order to further restrict the lit uid from collecting at thelower cdges oftlie plates, the said lower edges may be provided withdownwardly directed The edges of the perforations of the plates arepreferably rounded off, in order to facilitate the passage ofqtge 0plates ma be provided with surfaces of the ike, for t e purpose ofpreilutings or the venting the coating of the surfaces with liquid, andin order to divide and reunite the current of liquid as many times aspossible.

On the accompanying drawing one of the 5 preferred forms of constructionof the packing material according to my invention is shown, Figure 1being a front elevation, and Fig. 2 an end elevation.

n the drawings, a a represent the two oppositely inclined plates, whichare so arranged relatively to each other as to form a root with asubstantially horizontal ridge.

b I) represent the horizontal perforations of the plates.

f f represent the flutings on the surfaces of the plates.

d d represent the downwardly directed notches in the lower portions ofthe outer surfaces of the plates.

g g are notches in the upper portions of the outer surfaces of theplates.

-My improved packing bodies may be made of any length and they may bebuilt up in parallel rows, preferably arranged so as to alternate witheach other, or in rows crossing each other to form a grating, no specialsup ports being required. There is no possibility of the gases orliquids flowing directly and unimpeded through the chamber, tower or thelike, the liquid which runs down from any of the rows orlayers ofpacking material, being sure to be converted'into spray in the nextsucceeding lower layer. As compared with the usual Lunge plates, the newpack- 5 ing material presents the advantage of a fre uent change ofdirection of movement of t e geagents, of a uniform wettin of bothsurfaces of the plates, and of an increased duration of contact of thevarious reagents.

40 The plates are preferably iven such an inclination that the li uidwil trickle down in a uniform stream bot at the outside as well as atthe inside of the plates.

. My improved packing material is distinguished from an 'ular packingmaterial here tofore employe ed es or ridges are Vertically arranged,the sid es which meet to form said ridges being moreover not inclined soas to present a roofshaped structure. The said rior packing material,which, on account 0 the substantially rectangular inclination of itsnarrow end surfaces with relation to its front sides,-

could not be horizontally arranged, and was very deficient in stability,so that special supports, brackets, supporting rods or the like wererequired to secure them in place in the reaction chamber. Moreover theassemblage and building up of the said prior acking was difficult, andno abutting suraces or resistances from which the jets of liquid and ofas or vapors could rebound and become isintegrated, were provided, theli uid and gas on the contrary flowing throng the reaction chamber in asubstanin which the connecting seaeee tially vertical direction andwithout reacting sufiiciently upon each other.

As compared with the usual Lun e plates for filling reaction chambers,the fbllowing advantages are presented by the new filling bodies:

l. The manufacture of the new material is very easy and simple.

2. No special supports are necessary for packing the material, as thebodies of one row will constitute a perfectly stable support for thesucceeding upper rows.

The entire packing is more stable than with other plates; the packingmay be effected, so as to constitute a net shaped 3 structure. 7

4. The said bodies present more than double free sectional area than theplates.

5. For the same space of reaction chamher there is three times theacting surface, 35 the distance of the layers of plates in the usualplate tower of Lunge being taken to amount to about four inches only.

6. The liquid is retained in the chamber for a considerably longer time,inasmuch as the dripping down from a certain height, a drawback in theplate tower, is dispensed with. By this means the duration of the timeof reaction of gases and liquid is prolonged.

7. The gas current does not ascend vertically, but it is alwaysdeflected sidewise, also resulting in a longer duration of the gasreaction.

8. In the Lunge plates most of the liquid 00 remains on the top side ofthe plates, that is to say, at the )oints where a minimum of gas canpass, while on the lower side, where the gas impinges with great force,there is the least amount of liquid. In the new 05 packing body, bothparts are equally wetted.

9. In the Lunge plates the several jets of gas are directed parallelly u)ward, while in the new packing material t e gas jets are 10 directedagainst each other, resulting in a more thorough mixture and anincreased mutual reaction.

The packing material described may of course also be employed for gaswashin purposes, in themanufacture of alcohol and spirit and the like,and also for filling the c lambers employed for heating air and gases inthe operation of gas producer plants.

I claim:

1. Packing material for reaction and absorption chambers, etc,comprising oppositely-inclined perforated plates which meet at theirupper edges to form a substantially horizonta ridge.

2. Packing material for reaction and absorption chambers, etc.comprising two oppositely-inclined perforated side walls forming aroof-shaped body, the ridge at the mpacking 10 planes, the outersurfaces of the'walls having downwardly directed notches.

4. Packing material for reaction and absorption chambers, etc.,comprising two oppositely-inclined perforated side walls'forming aroof-shaped body, the ridge at the ins tersection of said wallsand thebase edges of l the walls being I in substantially parallel planes,-theouter surfaces of said walls being fluted;

5. Packing material for reaction and absorption chambers, etc.,comprising oppositely-inclined perforated plates which meet at their uper edges to form a substantially horizonta ridge, the perforations andbases of the lates being horizontal whereby they meet t e inclined facesof the plates at other than right angles. v

6. Packing material for reaction and ab sorption chambers,-etc.,consisting of plates united to form a roof-shaped structure havinghorizontal top ridges and provided with perforations which arehorizontal when said structure is set in upright position for use.

In witness whereof I'have hereunto set my hand in presence of twoWitnesses.
